Definitions

  • the present invention relates to a bagging machine to produce packaging items.
  • the machine comprises a forming shoulder to form a flat foil web into a foil tube, a transportation means to transport the foil tube, a fill pipe to maintain the foil tube and fill the packaging item, a longitudinal welding device to seal the web longitudinally, welding means to create cross seams and a separating device to separate the packaging items.
  • the invention further relates to a process to produce a bag that does not have a tabular shape.
  • the a. m. packaging machines are known to produce tabular bags.
  • a bagging machine is disclosed that allows to produce a tabular bag with four welded edges.
  • these bagging machines are not suitable to produce e. g. bags with at least one trapezoid cross section.
  • a bagging machine to produce packaging items, comprising a forming shoulder to form a flat foil web into a foil tube, a foil transportation means to transport the foil tube, a fill pipe to maintain the foil tube and fill the packaging item, a longitudinal welding device to seal the web longitudinally, welding means to create cross seams and a separating device to separate the packaging items, whereas the welding means and/or the separating devices are, at least partially, not perpendicular to the transportation direction of the foil tube.
  • the a. m. packaging machine allows to produce bags with a large variety of cross sections.
  • the inventive bagging machine is produced by and operated easily and costs efficiently.
  • the welding means and/or the separating devices are, at least partially, not perpendicular to the transportation direction of the foil tube.
  • the welding means or separating means have at least partially e.g. a curved shape and/or are tilted with respect of the transportation direction of the foil tube. More preferably the welding means and/or the separating devices are over the entire length, not perpendicular to the transport direction of the foil tube.
  • the welding means and/or the separating devices are rotatable around a vertical axis.
  • This embodiment of the present invention allows to produce, e. g. a bag with a trapezoid cross section.
  • the welding means and/or the separating devices are shiftable around a horizontal axis.
  • This embodiment of the present invention allows to produce e. g. bags with a trapezoid cross section, too.
  • the rotation or the shifting around the vertical or horizontal axis takes place after every welding of a cross seam.
  • the bagging machine further comprises side fold producers which are also, at least partially, not perpendicular to the transportation direction of the foil tube.
  • Another subject matter of the present invention is a process to produce a bag, whereas a flat foil web is formed into a foil tube, a longitudinal seal is applied with a longitudinal welding device and a first and a second cross seam is created with welding means and the bags are separated with a separating device, whereas the position of the welding means and/or of the separating devices is altered between the creation of the first and the second seam.
  • the welding means and/or the separating devices are rotated, preferably a horizontal or vertical axis.
  • first and second side folds are created by side fold producers and the position of the side fold producers is altered between the creation of the first and the second side fold.
  • Figure 1 shows a front view of the principle of the inventive bagging machine 1.
  • a flat foil web is unwound from a storage roler 3 and fed over a guiding roler to a forming shoulder 5.
  • the forming shoulder 5 has a asymmetrical form.
  • the flat foil web 2 is formed into a tabular form.
  • a foil removing means 6 is used to further transport the foil tube 8 and thus, the foil web in a transportation direction as indicated by an arrow 19.
  • the longitudinal welding device 16 allows to produce the longitudinal seal 15 as shown in figure 2.
  • the fill pipe 7 receives the foil web 2 which has been formed into a foil tube 8.
  • the jaws 9 of the transverse welding means 10 can be moved towards one another into and out of the plane of the drawing of figure 1 and are used to produce cross seams 11 (compare figure 2) on the foil tube 8.
  • a separating device 12 is housed in one of the jaws 9 in order to cut the foil tube 8 at each cross seam 11.
  • Two pair of side fold producers 14, 14' are provided on the transverse welding device 10.
  • the side fold producers 14, 14' are moved against one another (towards one another) and into the foil tube 8, which is between them in order to create side folds in the bag 13.
  • One pair of side folds is provided in foil transportation direction in front of the transverse welding device 10 and one pair is provided after the transverse welding device.
  • the transverse welding device 10 seals together the tips of the side fold, respectively.
  • the transverse welding device, the separating device as well as the side fold producers are not perpendicular to the direction of flow, but tilted by an angle ⁇ , which depends on the desired shape of the bag.
  • a bag with a rhomboid cross section i.e. a cross section shaped like a parallelogram
  • the a. m. means are rotatable around a horizontal axis (20) or around a vertical axis (17) by 180° a bag with a trapezoid cross section can be manufactured.
  • Figure 2 shows a bag with a trapezoid cross section.
  • the bag has one longitudinal seal (15) and two cross seams (11) each sealing together two foldings (not depicted).
  • Figure 3 shows a frequence of two produced bags 13 with a trapezoid cross section. It can be seen that, in order not to waste any packaging material, the bags are produced mirror symmectrically.
